I see no problem in it in that the two domains are very, very unlikely to be confused in context. Pretty much the only time confusion is likely to be sown is if there is a headlines akin to the one submitted here.

AFAICT, there's essentially no overlap of features beyond the fact that they're virtual file systems. The feature sets are completely different, and there's no intersection where if you read more than a few words into whatever you're looking at you'll be left scratching your head thinking "Oh jeez, which one is it this time?"
